Abstract
Abstract A multi-face clamp for wood working which comprises a clamping unit including a plurality of corner pieces. Each of the corner pieces defines at least two pressure faces which are adapted to engage complementary faces of a work piece. Two threaded bolts extend from and are operatively connected with the corner pieces. One of the threaded bolts has threads formed in an opposite direction from those of the other of the threaded bolts. A turn-buckle is disposed between each pair of adjacent corner pieces and receives in its inner threads the respective free end portions of the threaded bolts, so that upon turning of the turn-buckle the pressure faces of the corner piece exert pressure upon the complementary faces of the work piece.

A multi-face clamp for woodworking comprising a clamping unit including a plurality of corner pieces, each of said corner pieces defining at least two pressure faces adapted to engage complementary faces of a work piece, two threaded bolts extending from and operatively connected with said corner pieces, one of said threaded bolts having threads formed in an opposite direction from those of the other of said threaded bolts, a turn-buckle disposed between each pair of adjacent corner pieces and receiving in its inner threads the respective free end portions of said threaded bolts, so that upon turning of said turn-buckle the pressure faces of said corner piece exert pressure upon said complementary faces of said work piece, wherein at least one of said threaded bolts has a plurality of nuts, some of said nuts being adjustable along said of one said threaded bolts, and means on said corner piece for retaining said one of said threaded bolts selectively in a plurality of end positions.
Claim 3
Dependent Claim
109 words
The multi-face clamp, as set forth in claim 1, wherein said corner pieces comprise a plate bent to form a right angle therebetween and defining said pressure faces, an end portion extending from each end of said plate and bent to form a right angle relative to the adjacent portion of said plate, one of said end portions having an eye leading into an open channel, in order to permit insertion of one of said threaded bolts, and the other of said end portions extending into a flange having an eye receiving the other of said threaded bolts by means of a hook to form a swivel joint therebetween.
